Availability of PatentIn 2.1 Software
                     For Preparation Of Sequence Listings

For patent applications in which nucleotide and/or amino acid sequence
information is significant, many patent applicants are familiar with
submitting such sequence information prepared with the PatentIn
authoring tool. A general description of PatentIn is provided in MPEP
2430. While use of the PatentIn authoring tool is not required, the many
automatic features of PatentIn simplify generating Sequence Listings
when compared to generating them by hand in a word processing
environment.

The U.S. Patent and Trademark Office (USPTO) has developed a new release
of the authoring tool (Patentln 2.1) to aid in submitting Sequence
Listings in computer readable form in compliance with WIPO ST.25, the
PCT Administrative Instructions and 37 CFR 1.821 Ü 1.825. PatentIn 2.1
was developed through cooperation among the Trilateral Offices (USPTO,
EPO and JPO). PatentIn 2.1 is the latest release of the PatentIn
software and was designed to run on WINDOWSÌrm based operating systems.

Copies of the PatentIn version 2.1 software (two 3.5 inch diskettes per
set) and documentation can be obtained for $25 from the Office of
Electronic Information Products (OEIP), which may be contacted at (703)
306-2600 (voice) or (703) 306-2737 (telefax) or by email at
oeip@uspto.gov. The PatentIn version 2.1 software can also be obtained
for free by downloading from the USPTO's internet Web site
(http://www.uspto.gov).
